 ## Frame Rate
 
-The following aliases are defined for framerate values, either `-r` or `-framerate` parameters.
+The frame rate of an input image sequence can be specified using the `-framerate` option before the input.
+The frame rate can be specified as a decimal number or as a fraction. The following aliases are also defined
+for common frame rates:
 
-| ntsc | 30000/1001 | 29.97 fps equivalent. |
-| pal | 25| |
-| qntsc | 30000/1001 | VCD compliant NTSC |
-| qpal |  25 | VCD compliant PAL |
-| sntsc | 30000/1001 | square pixel NTSC |
-| spal |   25 | square pixel PAL |
-| film |  24 | |
-| ntsc-film |  24000/1001 | correct  23.98 |

-Is is prefereable to use a fractional rate, or one of the above settings where possible, for example `-r 30000/1001` is the more precise version of 29.97. 
+It is preferable to use the fractional representation or one of the above aliases for frame rates that aren't a whole number.
+For example `-framerate 30000/1001` is more precise than 29.97 and will prevent your video from slowly going out of sync over time.

-TODO Confirm no difference between -r and -framerate. -framerate seems a little more proper.
+You may also see `-r` used in some examples. The `-framerate` option is for manually specifying the frame rate for the image2 demuxer (which is responsible for handling image sequence inputs),
+whereas `-r` acts more generally on video streams and modifies existing frame rates by regenerating the frame timestamps or duplicating/dropping frames
+(depending on if it is used as an input or output option). For input image sequences, you almost always want `-framerate` over `-r`.

 Note, you want to control the number of frames to output, for a long sequence you would put the `-frames:v 100` before the "-i" flag, but here we are putting it before the output, since we want it to apply to the overall looping input, not the input sequence.
